Solar energy is free from noise and environmental pollution. It could be used to replace non-renewable sources such as fossil fuels, which are in limited supply have negative impacts. The first generation of solar cells was made crystalline silicon. They were relatively efficient, however very expensive because they require a lot purify the Nowadays, production has been improved since (thin-film cells, dye-sensitized perovskite organic cells). In this work, development discussed. advantages,...
The increased complexity of sample matrices resulted in the requirement specific and sensitive molecular recognition systems. Although imprinting is an old idea, its potential as tool analytical chemistry has been revived recent times. This review intended to comprehensively discuss evaluate progress applications molecularly imprinted polymers (MIPs) chemistry. A concise introduction for new readers field followed by comprehensive critical these developments MIP technology their divided into...
The antiperovskite Mn3+xNi1–xN compounds have been synthesized and characterized by a variety of experimental techniques. After Mn doping at the Ni site, both ferromagnetic characteristics an Invar-like effect were observed in antiferromagnetic host material. behavior was assumed to be related characteristic magnetic structure induced doping. Neutron diffraction results prove that stabilizes special Γ5g phase with strong spin–lattice coupling can tuned achieve behavior. magnetovolume (MVE)...
A baromagnetic effect in a novel tetragonal magnetic structure is introduced by vacancies Mn3 Ga0.95 N0.94 , due to the change of Mn-Mn distance and their spin re-orientation induced pressure field. This proven for first time antiperovskite compounds neutron powder diffraction analysis. feature will enable wide applications magnetoelectric devices intelligent instruments.
The organic solar cell (OSC) is a current hot topic in the context of energy related issues order to capture an economic and environmentally friendly manner from most abundant natural source, sun. However, efficiency OSCs achieved so far not up mark. Major components are electron acceptor material, such as fullerene, donor poly(3-hexylthiophene), P3HT. Fullerene ideal material but molecular level engineering P3HT required enhance OSCs. Optoelectronic properties can be improved by controlling...
Emergence of multidrug resistance (MDR) has limited the success chemotherapeutic agents. Reversal drugs efflux systems through combination therapy got wider attention for increasing anticancer efficacy. This study aims at co-encapsulation Paclitaxel with Naringin in mixed polymeric micelles enhanced activity drug. Drug-loaded were prepared using two different amphiphilic block co-polymers and characterized morphology, size, zeta potential, drug encapsulation, vitro release stability atomic...
Star-shaped polymers exhibit lower hydrodynamic volume, glass transition temperature, critical micelles concentration (CMC), and higher viscosity drug-loading capacity compared to their linear counterparts. In the present study, amphiphilic biodegradable 4-arm star-shaped block copolymers, based on poly(ethylene oxide) (PEO) as a hydrophilic part poly(ε-caprolactone) (PCL) hydrophobic segment, are synthesized by ring-opening polymerization of ε-caprolactone employing pentaerythritol an...
Meticulous structural elucidation and selectivity analysis of poly(ethylene ether carbonate) by multi-dimensional NMR.
1,4-Diazabicyclo[2.2.2]octane (DABCO)-based ionic liquids (ILs) 2-4 were synthesized by the N-alkylation of DABCO using alkyl halides varying chain lengths (C2, C5, and C7). The N-alkylated DABCO-ILs mixed with polyethylene glycols (PEGs) molar masses as hydrogen bond donors (HBDs) to prepare new deep eutectic solvents (DESs). These DABCO-PEG-based DESs successfully employed for synthesis a variety indoles 7a-7h (by Fischer indole synthesis) 1H-tetrazoles 9a-9i click chemistry). For...
This study was aimed at developing green histidine-modified Fe3O4 nanoparticles (His-MNPs) for the adsorptive removal of Acid Black 1 (AB1) from aqueous solution. The His-MNPs were characterized by atomic force microscopy, scanning electron microscopy-energy dispersive X-ray spectrometry, infra-red spectra and thermogravimetry. These MNPs spherical (average diameter 11-28 nm) with polydispersity index 1.40 about 13% mass coating histidine. To optimize AB1 adsorption on understand its...
